Ceramic Tumbling Media Applications

Ceramic media is recommended for general purpose polishing, light and heavy deburring, fast and extra fast deburring and ultra aggressive metal removal. Ceramic media is best for heavy cutting and hard metals. When a small media is required (under 3/4"), ceramics offer the best selection. Ceramic media supports very heavy parts better than plastic media.

Advantages of Ceramic Tumbling Media

Durable, inexpensive and highly versatile, ceramic finishing media is the most common media used in mass finishing. It can be manufactured in a wide variety of precise shapes, which assists in separation and elimination of lodging problems. Ceramic finishing media is made of silica and other minerals and abrasives that are combined, formed and fired at a high temperature, producing a very hard, cement-like product. Most ceramic preformed shapes, such as triangles, stars and ellipses, are extruded and cut to the desired length.

The density of ceramic preformed shapes is usually determined by the amount of abrasive incorporated into the mix prior to firing - the more abrasive, the higher the density. This is important because the higher the density, the more "aggressive" the ceramic media will be (faster cutting, rougher surface) and the quicker it will wear. Therefore, dense media is only practical where the objectives cannot be achieved any other way or where the reduction in cycle time brings a greater value than the extra cost in media consumption. The type and quantity of abrasive grain can be varied to accomplish particular tasks, depending on the bond selected.
